“…Figure 4(c) presents the diameter distribution of starch granules in OFSP, which covers a range from 3.4 to 13.5 µm with an average value of 7 µm. This is in line with previous observations of sweet potato starch granules, [37,38] ; however, it has been found that the granular size is highly dependent on the sweet potato variety.…”

Information on the content and bioavailability of provitamin A carotenoids, such as β-carotene, in plant foods is of great interest due to the widespread vitamin A deficiency in developing countries. While the amount of β-carotene can readily be quantified with analytical techniques, there is limited information on β-carotene morphology in native plant materials. Here, we introduce nonlinear microscopy for three-dimensional, label-free imaging of carotenoids in fresh and thermally treated plant tissues, providing quantitative information at single-aggregate level and detailed insight into their distribution. Carotenoids in orange-fleshed sweet potato (OFSP), carrot, and mango were visualized by coherent anti-Stokes Raman scattering (CARS) microscopy and, in the case of OFSP, related to the plant-matrix morphology by simultaneous second-harmonic generation (SHG) microscopy of starch granules. Sizes, shapes, densities, and location of different types of carotenoid bodies were quantified. While OFSP and carrot showed heterogeneous rod-shaped bodies with high carotenoid densities indicated by higher CARS signals, the carotenoid-filled lipid droplets in mango appeared as homogeneous low-density aggregates of rounded shape. In addition, β-carotene densities and morphologies in OFSP were studied after thermal processing, showing that the bodies remain intact despite significant changes of the surrounding starch granules.

“…Sweet potato has been widely consumed for its functions of delaying aging, improving immunity and preventing cancer. 1,2 Soluble solids mainly contain sugars, acids, vitamins and minerals, 3,4 which are the important indicators to determine the taste of sweet potato. Consumers generally prefer sweet potato with high and uniform soluble solid content (SSC).…”

Current global mortality from noncommunicable diseases (NCDs) remains unacceptably high and is increasing. A major reduction in the burden of NCDs should come from population-wide interventions, including the promotion of a healthy diet through the provision of adequate nutrition information on food labels. However, in order for this type of intervention to be successful, it is important to have a better understanding of the consumer. This review focuses on the need for food and nutrition labelling (the section of information on a food label that specifically declares nutrient content) within the context of NCDs, as well as consumer nutrition label use, and understanding and the impact of nutrition labelling on purchasing behaviour. It provides a summary of the latest global nutrition labelling trends, the current situation in South Africa and the way forward. Consumer knowledge, use and understanding of nutrition labelling has been investigated extensively in the international literature. However, the majority of these investigations were conducted in developed countries. Therefore, additional research on the impact of nutrition labelling in developing countries is necessary, and should be a priority. There have been many developments in South Africa in terms of food and nutrition labelling in the last decade. Although the food industry, health professionals and consumers face many changes, challenges and opportunities with regard to food, and specifically to nutrition labelling, this is also the ideal time to promote the use and understanding of nutrition information on labels by health professionals to consumers.
